Professional Applications & Engineering Value

This 4130 alloy steel tube end weld nut delivers critical performance advantages in hydraulic, pneumatic, and structural tubing systems where leak prevention and vibration resistance are paramount. The partially threaded design allows for easier installation on 3/4" OD tubing while maintaining full thread engagement through the 7/8" threaded portion. Engineered with UNF fine threading (5/16"-24), this weld nut provides superior resistance to loosening under dynamic loads, making it ideal for industrial machinery, fluid transfer systems, and mobile equipment applications. The combination of Class 2B thread fit and robust 4130 alloy material ensures reliable performance in high-stress environments where weld integrity and thread durability are critical to operational safety and maintenance intervals.

Specification Summary & Compliance

This tube end weld nut features 5/16"-24 UNF fine threading with Class 2B thread fit per UNF standards, ensuring precise dimensional accuracy and interchangeability. The 7/8" thread length and 1 3/8" overall height provide optimal engagement for 3/4" OD tubing with 0.065" wall thickness. Manufactured from 4130 alloy steel with right-hand, partially threaded configuration, this component is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting current environmental and substance restriction requirements for industrial applications.
